Microgrid with Fronius and Studer-innotec inverters, frequency shift

DIY

I have a 230 volt 3phase microgrid with 3 Studer xth-8000 inverters and two Fronius Symo, working really good, communicating through frequency shift.

I have a Victron MultiPlus-II 48/5000/70 230V connected to the microgrid.

Is it possible to make the MultiPlus-II behave the same way as the MG50 settings in the Fronius and stop feed-in when frequency is high ?

should be possible by using Gx device (Cerbo) and a node red control loop.
